Definitions

  • the invention relates to a wind turbine comprising enclosure structure and a method to manufacture said enclosure structure.
  • said conductive film layer is covered by a protective coating layer such as a PVC layer.
  • a protective coating layer such as a PVC layer.
  • said enclosure parts are electrically connected through a contact area on said enclosure parts such as by direct surface to surface contact, by flat spring to surface contact, by male/female connectors, by a conductive gasket or similar contact methods.
  • a contact area on said enclosure parts such as by direct surface to surface contact, by flat spring to surface contact, by male/female connectors, by a conductive gasket or similar contact methods.
  • said enclosure parts constituting said enclosure structure leaves no or substantially no holes in the surface of said conductive shield whereby its capability to protect against electromagnetic radiation is preserved.
  • said contact area preserves an effective electrically contact despite of changing ambient conditions such as vibrations, humidity and temperature.
  • said enclosure parts are electrically connected by conductive adhesive means.
  • said contact area preserves an effective electrically contact despite of changing ambient conditions such as vibrations, humidity and temperature.
  • said method to manufacture at least one enclosure structure of a wind turbine said conductive film layer is applied to said enclosure structure comprises steps of
  • said shield material is radar neutral material.
  • fig. 5a illustrates for one embodiment of a contact area exposed on one cover part
  • a low speed shaft extends out of the nacelle front and is connected with a wind turbine rotor through a wind turbine hub 4.
  • the wind turbine rotor comprises at least one rotor blade e.g. three rotor blades 5 as illustrated.
  • the wind turbine comprises a lightning protection system with the purpose of conducting the current of a lightning to ground potential 6 when the wind turbine experiences a strike.
  • the lightning protection system comprises receptors at the blade tip, a down conductor at the surface of or inside the blade or blades, a transfer area to a stationary part of the wind turbine, and a down conductor to ground potential 6.
  • Fig. 5a illustrates schematically one embodiment of a contact area 12 exposed on one cover part 7.
  • the main purpose of the contact area 12 is to establish an effective connection between attached cover parts 7 in order to form said Faraday cage that shield against incoming electromagnetic radiation.
  • a sufficient contact must be established along the whole contact area 12 between attached cover parts 7 as any hole or broken surfaces in the Faraday cage will limit its shielding capabilities dependent on the wavelength of the radiation i.e. the holes in the surface must be significantly smaller than the wavelength of the radiation that is to be kept out.
